is an uncommon species, found mostly in far southwest Utah and in adjacent areas of Nevada, inhabiting open, rocky places in semi-desert habitats. Plants produce relatively large and numerous bright green leaves, finely divided several times into flat, narrow, pointed leaflets. Leafless flower stalks rise above, growing upwards and at an angle, topped by bractless, compound umbels, typically of 10 to 20 rays, the individual clusters subtended by a few narrow, lobed bractlets. The small, five-petaled flowers are greenish yellow, with five exserted stamens. Fruits are bright green, flattened elliptical pods, lacking prominent ridges.
